Application
For installation of fire alarm systems, as well as for control and access control systems. They are mainly used for telecommunications inside the premises, both in dry and in wet places, as well as in the open air when using cables in special sheaths. These cables are suitable for use in telephone exchanges and switches for transmitting signals and data.
Typical design
Cable structure
1. Conducting vein: a copper wire with a diameter of 0,80 mm.
2. Insulation: low flammability polyvinyl chloride plastic compound. Core insulation is color coded.
3. Screen: aluminum-lavsan tape.
4. Runoff vein: copper wire.
5. Sheath: PVC plastic compound of red color of usual heat resistance.
Installation and operating conditions
Temperature range:
- during installation: -10 ° C ... +50 ° C;
- during operation: -20 ° C ... +60 ° C.
Bending radius: ≥ 12 cable diameters.
